If I understand correctly, you have 11 questions and you want to ask them once each in a random order. To do this, you could create a randomized list, and use-and-remove one item at a time. Here's a simple demo:

1) Create a new movie

2) Create a graphic member of some type and drag it onto the Stage

3) Create a movie script

4) Paste the scriptText below into the movie script

5) Run your movie

6) Open the Score window

7) Click on the Stage several times and watch how the playback head jumps about in the Score window
